1. Field of the Invention
The present invention relates to a lamp on sheet and manufacturing method thereof and more particularly to a lamp on sheet which is formed from a continuous strip of, for example, plastic laminated material in a manufacturing process.
2. Description of Related Art
It is well known that lamps have many shapes and functions depending on applications. Also, various methods are proposed for manufacturing one type of lamp in the art. Based on above, after considerable research and experimentation, the inventor of the present invention devises a novel method of manufacturing a desirable lamp on sheet.
It is an object of the present invention to provide a method of manufacturing lamps on sheets comprising the steps of pressing a continuous upper strip, an intermediate conductor assembly, and a continuous lower strip into a continuous strip assembly having a plurality of holes therealong being communication with the conductor assembly; mounting a light source assembly on the strip assembly to form a continuous strip of lamps; and cutting the continuous strip of lamps into a plurality of sheets each having at least one lamp wherein the conductor assembly is secured in the strip assembly. By utilizing this method, a mass production having the benefit of lower manufacturing cost is made possible.
It is another object of the present invention to provide a lamp on sheet comprising an intermediate conductor assembly including two parallel continuous strips of foils; a strip assembly including an upper strip having a plurality of holes therealong being communication with the conductor assembly and a lower strip; and a light source assembly wherein the strips of foils are secured between the upper and the lower strips.
In one aspect of the present invention, the strip assembly is selected from a PP, a PVC, a thin plastic material, a fireproof fabric, a glass-fiber, or an asbestos.
In another aspect of the present invention, the light source assembly is implemented as a plurality of SMD LEDs, LED dice bondings, LED Lamp or mini bulbs.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
The features of the first preferred embodiment of the invention are as follows: The bottom of conductor assembly 10 is covered by lower strip 22. Foils 11 and 12 are secured in each unit since upper and lower strips 21 and 22 are pressed firmly together. Hence, the possibility of short circuit caused by contacting the strips of foils 11 and 12 is substantially eliminated. Moreover, each unit has a better flexibility. Note that the order of performing steps 2 a and 3 a may be reversed in other embodiment, i.e., step 3 a performed prior to step 2 a is still applicable.
The features of the third preferred embodiment are the same as that of the first preferred embodiment. Thus a detailed description thereof is omitted herein. Note that the order of performing steps 2 c, 3 c and 4 c may be partially reversed in other embodiment, i.e., an order of performing steps 4 c, 2 c, and 3 c is also possible.
Note that in the second preferred embodiment, upper strip 21 is used as both mounting surface and securing surface. That is, light source assembly 30 is mounted on and secured to upper strip 21. Further, in the third preferred embodiment the mounting surface is lower strip 22 (i.e., light source assembly 30 is mounted on lower strip 22 which is contrary to that of the second preferred embodiment in which strip assembly 20 is inverted prior to mounting light source assembly 30). But the securing surface is upper strip 21 in both second and third preferred embodiments. It is noted that the constructions of conductor assembly 10 and strip assembly 20 are the same in both second and third preferred embodiments with the only difference of requiring the formed continuous strip assembly 20 by laminator 90 to invert in the manufacturing process prior to performing the step of mounting light source assembly 30 on lower strip 22.
It is also noted that conductor assembly 10 may comprise a plurality of pairs of continuous strips of foils 11 and 12 for increasing the illuminant effect thereof in other embodiment. Moreover, the lamination process performed in laminator 90 may be effected by direct heating, high frequency heating, or adhesive heating for securing conductor assembly 10 in the continuous strip assembly 20.
In brief, the characteristics of the invention comprise an intermediate conductor assembly 10 including two parallel continuous strips of foils; a strip assembly 20 including an upper strip 21 having a plurality of holes therealong being communication with the conductor assembly 10 and a lower strip 22; and a light source assembly 30 mounted on the strip assembly 20 to form a continuous strip of lamps. The benefits of the lamp of the invention are detailed below. It is easy to manufacture. The securing of conductor assembly 10 and light source assembly 30 is reliable. The strip assembly 20 is maintained well during the securing process of light source assembly 30, thereby preserving an appearance of the lamp of sheet. Most importantly, its quality is high.
While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
